FRICTION-SUPPORT FOB, LIDS.

Specification of Letters Patent.

Patented June 15, 1920.

Application filed December 4, 1919. Serial No. 342,3d5.

To all whom it may concern:

Be it known that I, ISAAC F. BURTON, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inFriction-Supports for Lids, of which the following is a specification;

One object of my invention is to provide an improved friction supportfor lids which will be particularly adapted for use in connection withthe hinged lids or covers on talking machine cabinets and will be soconstructed that it will hold the lid or cover in various pivotalpositions into which it is manually moved.

Another object is to so construct my invention that the supporting baris free to move in various paths relatively to its friction engagingmeans so that various parts of said engaging means will be presented tosaid bar and thereby prevent the .bar from wearing a groove in thefriction engaging means which would soon cause the friction engagingmeans to lose its grip upon said bar.

Another object is to make my invention of a simple and durableconstruction and i so that the amount of friction exerted between saidfriction engaging means and said bar can be readily adjusted.

A further object is to so construct my invention that it can be easilyand quickly made and placed in position.

These objects, and other advantageous ends which will be describedhereinafter, l attain in the following manner, reference being had tothe accompanying drawings in which Figure 1 is a sectional elevationtaken on the line 1-1 of Fig. 2 showing my invention applied to atalking machine cabinet and illustrating a lid or cover in a closedposition,

F ig. 2 is a sectional elevation taken on the line 2'2 of Fig. 1, drawnon a smaller 'scale and illustrating in full line position the lid in araised position and in dot-anddash line position, the lid closed,

Figs. 3 and if: respectively represent face and edge views of the lidsupporting bar shown in Figs. 1 and 2,

Fig. 5 is a face view of one of two friction ererting pads which form apart of my mventlon,

Figs. 6 and 7 are face views of two side plates which form a part of myinvention and between which the friction pads are adapted to bepositioned,

Fig. 8 is a side view of a hanger bracket which is preferably employed,and

Fig. 9 is a top plan view of a slotted facing plate which 1 preferablyuse.

Referring to the drawings, 10 represents a structure illustrated in theform of the body portion of a talking machine cabinet and 11 representsa lid which is pivotally connected to the body portion 10 by hinges 12.A partition or ledge 13 is included in the body portion 10 and thispartition has a slot li formed therein and the slot 14: can be madecomparatively wide and covered by a facing plate 15 which has acomparatively narrow slot 16 therein. A. hanger 17, which is preferablymade of a piece of flat strip metal bent into the form shown in Fig. 8,has its upper extensions 18 secured to the partition 13 by means ofscrew bolts 19; said screw bolts passing through the partition and alsoserving to hold the facing plate in position, as clearly shown in Fig.2.

The bottom of the hanger 17 has a slot 20, and a lid supporting bar 21extends upwardly through the slot 20 and through the slots 1% and 16 andis pivotally connected at 22 to a fixture 23 which is screwed to theinner surface of the lid 11. Two friction pads 24; and 25 fit the spacewithin the hanger l7 and are located one adjacent each wide face of thebar 21. These friction pads may be made of leather or other suitablematerial and as illustrated are of rectangular form as shown in Figs. 2and 5. Two plates 26 and 27 are positioned adjacent the respective outerfaces of the pads 24 and 25; the plate 26 having two separated roundholes 28 while the plate 27 has two angular holes 29 which are alsospaced apart as shown in Fig. 6. The plates 26 and 27 are preferablymade smaller than the pads 24 and 25 so as not to touch the sides or thebottom of the hanger 17 when placed in the position shown in Figs. 1 and2.

Each of the pads 24 and 25 has two holes 30 which are spaced apart andtwo clamping bolts 31 are adapted to be inserted through the holes 28,29 and 30 of the above mentioned plates and pads, as clearlyillustrated, said clamping plates having angular portions 32 adjacenttheir heads 33 which fit within the angular holes 29 of the plate 27 soas to prevent rotation of said clamping bolts.

Thumb nuts 34 are fitted on the clamping bolts 31 and coiled springs 35are interposed between the thumb nuts 34; and the plate 26. The clampingbolts 31 are thus spaced a comparatively great distance apart or inother words are spaced apart a distance which is greater than the widthof the supporting bar 21. The lower end of the supporting bar 21 has apin 36 projecting therefrom and adapted to engage the lower surface ofthe bottom of the hanger 17 to limit the upward pivotal movement of thelid 11 on its hinge 12. The amount of friction exerted by the pads 24:and 25 against the supporting bar 21 can be varied by adjusting thethumb nuts which are located in a convenient position and this frictioncan be maintained at all times sufficient to hold the lid in any of itspivotal positions into which it is manually raised. For example, if itis desired to only partly raise the lid, the friction will be suflicientto hold the lid in its partly open position. If the lid to be supportedis extremely heavy, the thumb nuts 3 1 can be turned inwardly toincrease the friction and in this manner the device can be adjusted tosuit lids of various weights. As is obvious from the full anddot-and-dash line positions of Fig. 2, the supporting bar 21 is free toswing, during its raising or lowering positions, between the clampingbolts 31. In view of this construction the bar 21 will seldom move twicein the same path and therefore will not act to wear grooves in theadjacent faces of the friction )ads; 1 By making the plates 26 and 27slightly smaller than the interior of the hanger 17, the plateswill haveno metallic contact with the hanger and the device will practically benoiseless in its operation.

By the use of my invention not only can the lid be held in any pivotalposition as above described but by means of the 0011- struction andarrangement of the parts, said parts can be adjusted so that the lidwill stay all the way open and when the user wishes to close the lid hecan do so by giving it a slight push downward and it will then fallquietly to its closed position due to its own weight.

While I have described my invention as taking a particular form, it willbe understood that the various parts of my invention may be changedwithout departing from the spirit thereof, and hence I do not limitmyself to the precise construction set forth, but

consider that I am at liberty to make such changes and alterations asfairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A device of the character describedincluding a supporting bar; friction producing means having a surfacefor engagement with and of greater width than said bar whereby thelatter can move unobstructedly in the direction of its width and lengthrelatively to said surface of the friction means; and means for holdingsaid surface of the friction means in engagement with said bar;substantially as described.

2. A device of the character described including a supporting bar; afriction producing pad having a surface for engagement with and ofgreater width than said bar; means forming a support for said frictionpad and including a slot through which said bar extends, said slot beingof a width greater than the width of the bar whereby the bar can moveunobstructedly in the direction of its width and length relatively tosaid surface of the friction means and its support; and means forholding said surface of the friction means in engagement with said bar,said holding means including parts located at opposite sides of the pathof movement of said supporting bar; substantially as described.

3. A device of the character described including a supporting bar; asupporting hanger having a slot in its bottom; friction pads mountedwithin said hanger and located adjacent opposite faces of said bar, saidfriction pads having surfaces for engagement with the opposite faces ofand of greater width than said bar; clamping bolts extending throughsaid friction pads at opposite faces of said bar; adjusting nuts on saidbolts; and springs interposed between said nuts and said friction padsfor holding said pads in frictional engagement with said bar, said boltsbeing located a distance apart greater than the width of said barwhereby the latter can move in the direction of its width and lengthrelatively to said friction pads; substantially as described.
